1, semiconductor refers to the material whose conductivity is between conductor and insulator at room temperature. Semiconductors have applications in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting, high-power power conversion and other fields. For example, diodes are devices made of semiconductors. No matter from the perspective of science and technology or economic development, the importance of semiconductors is enormous. Most electronic products, such as computers, mobile phones or digital recorders, are closely related to semiconductors. Common semiconductor materials are silicon, germanium, gallium arsenide and so on. Silicon is one of the most influential semiconductor materials.
2. Photovoltaic is the abbreviation of solar photovoltaic power generation system, which is a new type of power generation system that directly converts solar radiation energy into electric energy by using the photovoltaic effect of solar cell semiconductor materials. There are two modes of independent operation and grid-connected operation. At the same time, solar photovoltaic power generation system is classified as centralized, such as large-scale northwest ground photovoltaic power generation system; One is distributed (bounded by >: 6MW), such as photovoltaic power generation system on the roof of industrial and commercial enterprises and photovoltaic power generation system on the roof of residential buildings.
Operating environment: Huawei nova 6(5G) and HarmonyOS system 2.0.0.
